[Nook Color General] disneygirl74:
Ok, I'm going to give throwing my two cents in here a shot. I'm not a terrible newb. in general sense, but in this regard, I am. I was always too chicken to root anything, though it was certainly tempting. My husband has no interest in tech stuff and I couldn't imagine having to tell him "oops I bricked my brand new phone" if it happened. :eek:

I have my Nook Color running on CM 7.1.0 RC1, booting from SD only. I upgraded from 7.0.3 when it came out and I do like it better. I talked my sister through the same process with the same version and we are both using PNY 10g Class 10 8gb cards from Best Buy. Mine has been ok. Some glitches, force closes now and then and speed you wouldn't exactly rave about, but I could mostly handle it. I've been able to copy/paste video through ES file explorer from a networked computer and watch it on my device without issue, as well as play angry birds, remote other computers via android-VNC etc. My gmail app has been a bit painfully slow. Hers on the other hand is barely useable (so I'm told). I found this early this morning and read pages upon pages of it thinking wow, this changes everything, so I grabbed the card out of my phone and switched them out. After after running a few CDM tests, I'm not sure what to think, though.

I'm now running CM7 on my Sandisk Class 2 16g card that came with my OG Droid. The thing is, so far, it does *seem* better, but the tests don't exactly reflect it in this case. (though it's entirely possible I'm missing something) I have a bunch of various SD Cards, but I just tested a few for now.

*So isn't this supposed to be better than the Sandisk I'm using now?

I'm going to try and use it a lot today to do various stuff. I know there were a couple of force closes when doing all the set up, which may mean nothing and ADW launcher gave me an error a little while ago, but so far in general things seem better. I guess time will tell. I'm definitely considering buying a Class 4 Sandisk, but I've spent a lot of cash as it is, lately. I'm not even sure if there's a point or not now.
